This is a complicated problem. Some tracks have curfews (unlike Vegas) and can't run early/late. That pushes you toward three days. Many people work and can't justify all the days off, especially if you add in a long (8 - 10 hour) schlep to/from the track. That pushes you toward two.

Every class you don't run will complain. Especially with grade points making it so you need the divisionals to get into the nationals.

This is a hard problem. Not sure there's an easy answer.
